I found that I had the brackets screwed together wrong when I first noticed that......you may not have the same problem, but once I fiddled around with the brackets, I got everything to clear the front 3/4" tube by a 1/2" or so when closed.
I had more of a problem with the outside edge of the hoop interfering with the hood seal, and getting the hoop to lay flat against the hood. I ended up cutting off the upper portion of the hoop just above the air shock mounts and trimming the edges to miss the seal. This alowed me to bend and twist the hoop to lay perfectly flat against the hood. Some re-weld the upper portion of the hoop back on, but I found it unnessesary.
At first I bonded the hoop to the hood with 3M HSRF, but found later that it was too brittle and it seperated from the hoop (maybe the mix wasnt perfect?) so I ended up using the button head screw method.
If/when I do it again I plan on counter sinking some screws into the surface of the hood, then bonding/screwing the hood to the hoop and HSRFing the screw heads to make them invisible.
